I've been staring at my 125 Lake Tanganyikan community tank for a while now and was wondering why do certain fish hang out where they do? It's kind of funny, certain fish roam the tank while others stay in one spot or another. The light is consistent across the tank, i have two canister filters one on either side of the tank and also have two water movers on either side of the tank. Ive tried switching things on and off on different sides of the tank with no change.
I think it's interesting.
